The prince's own lands: the island of Rügen with the Rugard by Bergen (his residence since about 1180), the ruined temple fortresses of Arkona and Charenza (Garz), and Hiddensee; on the mainland the land of Barth, the Strelasund shore where the fishing place of Strale lies (Stralsund gets town rights in 1234), the land of Gristow north of the Ryck, and the Ryck mouth where he founded Eldena in 1199 with land on both banks.
He also claims the land south of the Ryck (Gützkow, Wusterhusen) that he held in the 1190s and lost to the Pomeranian dukes in 1198; the Tribsees land is drawn as contested (Tribsees land).
